FOUNTAIN ROLL ()LEANERv Application filed February 16, 1931.

This invention relates to the fountain roll of an ink fountain and is particularly adapted for ink fountains used in newspaper printing machines.

The principal objects of the invention are to provide means for taking off particles of paper or other foreign substances that get on the fountain roll and keeping them from falling back into the ink and more specifically to provide a scraper which will remove pieces of paper and other dbris and yet allow the ink to return to the fountain.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which Fig. 1 is a side view of an ink fountain broken away in section to show a preferred embodiment of this invention;

Fig. 2 is a plan of the same, and

Fig. 3 is a side view looking in the direction of the arrow 8 in Figs. 1 and 2.

This invention is shown as applied to the usual ink fountain 10 which delivers through a fountain roll 11 to a pick-up roll 12 which in turn contributes a supply of ink to the various inking rolls and cylinders. The rest of the inking train is not shown herein.

The fountain roll 11 revolves in the fountain in the direction of the arrow shown in Fig. 1. The usual fountain back 13 is shown carrying a fountain blade 14: for regulating the amount of ink delivered to the pick-up roll 12 and eventually to the plate cylinder. This blade is not disturbed according to this but on the other side of the fountain a double hinge 15 is secured for pivoting the usual cover plate 16 and a scraper 17 The cover plate, being comparatively heavy, assists in holding the scraper down against the roll 11.

The scraper 17 is of a finger-like construction having a series of fingers which may be spaced apart any desired distance to suit the desired conditions. By putting the adjacent fingers close together very small pieces of foreign matter will be kept out of the foun tain. Even though pieces of paper or the like are stuck quite closely to the fountain roll, these fingers will catch and loosen them Serial No. 516,015.

N. Y., ASSIGNOR TO Woon NEWSPAPFJR or NEW Yoax, N. Y., A con-roanrrron or VIRGINIA and they will slide down the incline into'the concave bowl 18 at the bottom. This bowl is, of course, flat across and the paper ordinarily 1s left in it, but the ink gradually drains out ofitand drips back into the fountain.

The cover plate 16, of course, prevents for- 61 Il matter from getting into the fountain at the top but it does not prevent the paper on the fountain roll from coming aroundi and being deposited in the ink.

The principal disadvantage of these pieces of paper, however, is that they cause trouble in the regulation of the thickness of ink on the fountain roll by sticking closely to it and coming up on the other side under the blade 14 and inoving that up. This allows an in-- crease in the thickness of the ink for a considerable distance along theroll.

Although I have illustrated and described only one formof the invention I am aware of the fact that modifications can be made thereinby any person skilled in the art without departing from the scope of the invention as expressed in the claims. Therefore, I do not wish to be limited in this respect but what I do claim is 1. The combination with an ink fountain and its roll, of a scraper on the return side of the roll comprising a series of fingers spaced apart for engaging moving foreign matter therefrom.

2. The combination with an ink fountain, a fountain roll and a fountain blade on the delivery side of the roll for regulating the amount of ink delivered by the roll, of a series of finger-like scrapers on the back of the roll extending upwardly into contact with the surface of the roll for removing particles adhering to the roll and directing them downwardly and holding them out of the Y ink in the fountain.

3. The combination with an ink fountain and its roll, of a cover plate pivoted to the wall of the fountain for covering the fountain between the roll and the wall of the the roll and re-v with a fountain roll and a pivoted series of fingers, each having a concave portion and an upwardly extending portion for engaging the fountain roll and scraping particles from the surface thereof, whereby said particles will flow down into the concave portion and the ink will be drained therefrom, said fingers being spaced apart along the fountain roll.

5,; The combination with an ink fountain and its roll, of a cover plate pivoted to the wall of the fountain for covering the fountain between the roll and the wall of the fountain and a scraper also hinged to the fountain under the cover plate, said cover acting to hold the scraper down against the surface of the fountain roll.

In testimony whereof I have hereunto affixed my signature. HENRY A. WISE WOOD.
